5. Open the main drain and collect solution in clean containers or recovery tank for re-use
in system.
6. After the system is completely drained from the main drain, open any low-point drains
to remove the remaining solution from the system.
C. Placing the System in Service (after it has been completely drained):
1. Close the main drain valve on the riser.
2. Connect the propylene glycol/water solution fill pump (NOT the CS-1 pump) to the con-
nection located on the main drain assembly.
3. Close the main drain valve, vent/bleed valves, and low-point drains if opened. Ensure
there are no openings on system piping.
4. Fill system with Firefighter Eliminator C or Eliminator F propylene glycol/water solution.
While filling, periodically open the manual vent/bleed valves or allow the Model AV-1
Vent Valve to automatically open on system piping to ensure air is eliminated from sys-
tem piping. Slow fill is recommended to minimize the entrainment of air.
5. Fill and pressurize system piping to 50 PSI (3.45 Bar) minimum using the CS-1 Pump
system to provide the final set system pressure.
6. Check for trapped air by cracking open vent/bleed valves or observe the AV-1 Vent
Valve. Ensure all trapped air is eliminated from the system.
7. After system pressure is attained, the water supply control valve up stream of the deluge
valve can be opened.
